Investigation on the Effect of Dynamic Frequency on Fracture Evolution in Preflawed Rock under Multistage Cyclic Loads: Insight from Acoustic Emission Monitoring

Figure 4

The relationship between the maximum strain and dynamic cyclic number. (a–c) Plots of the maximum axial strain (a), maximum lateral strain (b), and maximum volumetric strain (c) against cyclic number at a fatigue loading stage. (e, f) Plots of the cyclic axial, lateral, and volumetric strain against fatigue loading stage.
